Abstract
The invention aims to provide an efficient copper-nickel polymetallic sulphide ore beneficiation reagent. The traditional Chinese medicine is prepared from the following raw materials in parts by mass: 0.05-0.40 diesel oil, 0.80-1.30 liquid butyl ammonium black, 0.30-0.80 isopropyl ethyl thiourethane and 0.20-0.60 nitrogen nitrile ester. By applying the agent in the beneficiation of the copper-nickel polymetallic sulphide ore, the content of magnesium oxide in the copper-nickel bulk concentrate can be reduced, the metal recovery rate of the copper-nickel polymetallic sulphide ore can be obviously improved, the existing copper-nickel mineral resources can be fully and efficiently utilized comprehensively, the service life of a mine is prolonged, and good economic benefit and social benefit are created.
Description
Technical field
The present invention relates to a kind of beneficiation reagent that copper nickel multi-metal sulfide ore dressing process uses that is used for, is exactly a kind of beneficiation reagent that complicated difficulty is selected copper nickel multi-metal sulfide that is suitable for specifically.
Background technology
Mineral resources are important substance bases of economic construction and social life.Current, because fast development of national economy, the demand of mineral resources is in quick sustainable growth state always.Along with large-scale exploitation utilization; Make important coloured mineral resources dilution day by day, complicated of China; Based on present poor, assorted, the difficult present situation of important coloured mineral resources; Each coloured enterprise all need seek collecting power strong, select that performance is good, consumption is few, environmental pollution is little, and can significantly improve the efficient beneficiation reagent of beneficiating technology index, to increase the business economic benefit.
For copper nickel multi-metal sulfide; Traditional collecting agent commonly used mainly contains: xanthic acid salt (like butyl xanthate, amyl group xanthate etc.), D2EHDTPA salt (like aerofloat 226 etc.); These collecting agents such as xanthate class collecting power are strong, but selectivity is relatively poor, and the concentrate product quality is lower; Though black powder class selectivity is better, it is often undesirable to be used for sorting the process major metal rate of recovery.The appearance and the application of ester class (like thiourethane, xanthate etc.) medicament; Make the more above-mentioned medicament of beneficiating technology index have than much progress; But select copper nickel multi-metal sulfide for containing high contents of calcium and magnesium and containing the higher complicated difficulty of chlorite, serpentine that is prone to floating easy argillization; Use above-mentioned medicament to be difficult to obtain the satisfied technical indicator that sorts, this has just caused the large strategic non-ferrous metal in short supply of China can not obtain efficient comprehensive reutilization, causes the huge wasting of resources.
Summary of the invention
The object of the present invention is to provide a kind of efficient copper nickel multi-metal sulfide beneficiation reagent.
The efficient copper nickel of the present invention multi-metal sulfide beneficiation reagent is to be processed by the raw material of following quality prescription: 0.05～0.40 diesel oil, 0.80～1.30 liquid aerofloat 226,0.30～0.80 isopropyl ethyl thiourethane and 0.20～0.60 sulphur nitrogen nitrile ester.
Wherein diesel oil is general diesel oil, and its excess-three kind component is commercial grade.
The compound method of medicament is according to above-mentioned formulation content, and sulphur nitrogen nitrile ester and isopropyl ethyl thiourethane are added respectively in the liquid aerofloat 226, adds diesel oil again, stirs 10～30min and gets final product.
The method for using of said medicament: will directly make an addition to the operation of roughly selecting that difficulty is selected copper nickel multi-metal sulfide by the oily liquids medicament of above-mentioned compound method preparation.
Medicament of the present invention is compared with other conventional floating agents, and the present invention has the oligosaprobic characteristic of high-efficiency low-toxicity, and the medicament action effect is good; Can significantly reduce being present in the floating collecting that is prone to the argillization gangue mineral that is prone in the base property ultrabasic rock, reduce the content of magnesia in the copper-nickel concentrate, improve the difficult metal recovery rate that selects copper nickel multi-metal sulfide; The production simple and convenient preparation; Production cost is low, only need the chemical products of several kinds of commercial grades be carried out simple mixed processing in proportion and get final product, and addition is few; It is convenient to add, and has characteristics such as collecting frothing capacity concurrently; Be particularly useful for complicated difficulty and select copper nickel multi-metal sulfide, it is big effectively to have solved the conventional dose consumption, and the actual conditions that environmental pollution is serious have realized that environmental protection and raising the output economic benefits and social benefits should.
Through the application of medicament of the present invention in the ore dressing of copper nickel multi-metal sulfide; Can reduce the content of magnesia in the copper nickel bulk concentrate; Can improve the metal recovery rate of copper nickel multi-metal sulfide significantly; Produce resource to fully utilize existing copper nickel fully efficiently, prolong mine life, create good economic benefit and social benefit.
The specific embodiment
Following embodiment can further specify the present invention, but does not limit the present invention in any way.
The prescription of the embodiment of the invention 1-embodiment 4 is formed and every kind of pharmaceutical quantities (the preparation total amount is 160g/t) of four embodiment is seen table 1, and wherein diesel oil is general diesel oil, and its excess-three kind component is commercial grade.
Table 1
According to the preparation of the ratio in the above table, wherein diesel oil is general diesel oil, and its excess-three kind medicament is commercial grade, during use sulphur nitrogen nitrile ester and isopropyl ethyl thiourethane is added respectively in the liquid aerofloat 226, adds diesel oil again, stirs 10～30min and gets final product.
The method for using of said medicament: will directly make an addition to the operation of roughly selecting that difficulty is selected copper nickel multi-metal sulfide by the oily liquids medicament of above-mentioned compound method preparation.
